Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187610, here are decompositions:

13 + 187597 = 187610
37 + 187573 = 187610
79 + 187531 = 187610
97 + 187513 = 187610
103 + 187507 = 187610
139 + 187471 = 187610
193 + 187417 = 187610
223 + 187387 = 187610

Showing the first eight; more decompositions exist.
